Situations where such planets could exist include a young terrestrial planet just after its formation, a planet that has recently suffered a large collision event, or a planet orbiting very close to its star, causing intense irradiation and tidal forces.

Orbiting close to their parent star, the intense stellar irradiation could melt the surface crust directly into lava.

The entire illuminated surface of a tidally locked planet could be left covered in lava oceans while the dark side may have lava lakes, or even rock rain caused by the condensation of vaporized rock from the hotter side.
